SPECIFICATION zoning part of Letters Patent No, 313,678, dated MarchApp'icati n filed October 13, 1-84. (No nrozlcl To all whom it mayconcern:

Be it known that I, MARION A. Vaterbury, in the county of New Haven andState of Connecticut, have invented a new 5 Improvement in \lViclchereby declare the following, when -'-taken in connection withaccompanying drawings and the letters of reference marked thereon, to beafull, clear, and exact description of the same, 1 and which saiddrawings constitute part of this specification, and represent, in

Figure 1. a side view of a wick adjuster; F wick-tube, showing a horizwick-adjusting device; Fig.

tral section; Fig. 4, a modifi justing-cylinders This invention relatesto a Wick-adjuster such as employed to adjust the wick in oil- 2 stoves.The wick in this class of burners is necessarily broad.

Wick-adjusters of various kinds have been employed. That more generallyin use consists of several sharp-toothed wheels, similarto the wheelsused in lamp-burners; but with such wheels it is difficult toconveniently adjust the wicks, for if there be a greater resistance tothe movement of the wick at onepoint than another the wick yields to theteeth of the wheels, and under such resistance holds back from propermovement. In other cases a pair of cylinders have been arranged one eachside the wick, the cylinders geared together, so that by the rotation ofthe cylin- 5 ders the wick will be adjusted; but a serious difficultyattends the use of these cylinders, as to work properly they necessarilybind so hard upon the wick as to force the oil from the wick in raisingand interfere materially 0 with the proper draft of oil to the flame. Inother cases the cylinder has been used on one side of the wick withratchets on the other; but in such an arrangement the teeth of theratchets catch the threads of the wick and in- 5 terfere with the properadjustment.

' The object of my invention is the construe tion of a wick-adjusterwhich will overcome such difficulties; and it consists in a pair oftransverse shafts-one each side of and par- -tube with ontal view of the3, a vertical cencation of the ad- MoRRIs, of together.

Adjusters; and I do I allel with theplane ofthe wickthe two geared 50and each carrying a short cylinder arranged to impinge upon the wick atdirectly-opposite points, the one cylinder constructed with an annularrib on its periphery, its companion cylinder on the other shaft with acorresponding annular groove, and as more fully hereinafter described.

The two are arranged transversely through thewick-tubeone at each sideand parallel with the plane of the wick. One ofthe shafts, B, is fitted with a head, it), by which it may beconveniently rotated, and the two are geared together by toothed wheelsE E.

On the shaft B two or more cylinders, F F, are fixed, presenting a shortcylindrical surface, and upon the other shaft, 0, are correspondingcylinders, G, cylinders on the other shaft, and so that the wick passesup between the said cylinders, the cylinder on one side bearing uponthat side of the wick against the cylinder upon the opposite side as aresistance. One cylinder of each pair is constructed with an annular ribon its periphery, and the other cylinder of the pair with acorresponding groove, b, which enables the cylinders to make a firm gripupon the wick. \Vhen the shafts are rotated, the cylinders worksimultaneously, and, bearing upon opposite sides against each. other,conveniently and perfectly adjust the wick, and without interference ofthe flow of oil.

The bearing-surface .issul'ficient to firmly grasp the wick, and thehearing may be so great as to force the oil entirely from the wick atthe point where the cylinders bear; but this will be recovered as thewick passes above the cylinder by absorption from the adjacent oportions of the wick.

To incl ose the adjusting devices in the wicktube, a chamber, H, isformed in each side of the wick-tube, in which the adjusters will work.
